Yes you can certainly have polished concrete in your bathrooms, but you should do additional sanding to prevent slippage. Polished concrete can look nice in bathrooms, there’s no grout so it gives a very clean look. A large amount of water does not damage the concrete. It is not only cheap but also lasts longer than other premium floorings. It is available in different styles and colours and gives a modern look. Also, it is easy to clean and sweep concrete floors in the bathroom.
